The Lowdown
Righto, let’s have a look at what’s shaping up for Jaconé. This is a decent stretch of exposed beach, and we’ve got a solid run of Southern Hemisphere groundswell rolling in over the next few days, with good winds to match. The water temperature is sitting at 74°, which is a touch warmer than normal for this time of year – nothing wild, but you’ll notice it’s a little more comfortable than usual.
The main event kicks off Tuesday afternoon, 11 August. The morning is a bit of a write-off – that 8 ft S swell is getting chopped up by a cross-shore wind, and it’s only marginal. But by the afternoon, the wind swings light cross-offshore from the east, and the swell builds to 10 ft out of the south with a 13-second period. That’s a lot of water moving – combined swell energy is strong at 3082. This is big, powerful, and clean. Only for experienced surfers, this one. If you’re not confident in overhead-plus waves with a bit of push, sit this one out.
Wednesday the 12th stays solid, with 8 ft S swell and a 12-second period. The morning is clean under a cross-offshore east-northeast breeze, and the energy is still strong at 1523. Good conditions for experienced surfers, but the wind picks up a touch in the afternoon, so the morning is the pick.
Thursday the 13th, we get a proper offshore wind from the north-northeast in the morning, light, with 7 ft S swell and a 12-second period. Combined energy is 1339 – still strong. This is clean, lined-up, and inviting for anyone who’s comfortable with solid head-high sets. The afternoon turns cross-shore and a bit bumpy, so go early.
Now, Friday the 14th – this is the standout. The morning is glassy. Dead calm. Westerly breeze at 3 mph, and the swell holds at 7 ft out of the south, 13-second period, with 1526 combined energy. That’s a rare window of absolute clean conditions on a solid, long-period groundswell. For experienced surfers, this is as good as it gets. The sets will have real shoulders, and the paddle-out will be manageable with those longer gaps. Get on it.
Saturday the 15th still has good energy – 7 ft S swell, 13 seconds – but the morning is clean under a cross-offshore breeze, while the afternoon gets messy with a risk of thunderstorms and a strong cross-shore wind. Sunday the 16th drops off to 4 ft, but the morning offshore wind from the northeast keeps it clean and fun for mid-lengths or a log.
From Monday the 17th, the swell direction shifts east and the periods drop to 8 seconds – short-period windswell. The energy drops into the moderate range (803 down to 327). The conditions stay clean with offshore or cross-offshore winds through to Tuesday the 18th, but the waves are weaker and more crumbly. Still surfable for the keen, but nowhere near the quality of the first few days.
Then we hit a dry spell. From Wednesday the 19th through to the end of the period, the swell drops to below 3 ft, winds are onshore or cross-onshore, and the energy is weak (71 to 252). There’s a brief flicker on Saturday the 22nd with 5 ft S swell and glassy conditions in the morning – that could be fun for a grovel session – but otherwise, it’s a flat and choppy stretch. By Tuesday the 25th, a small 5 ft easterly windswell shows up with offshore winds, but it’s short-period and marginal.
So, the best of the 16 days is Friday morning, 14 August – glassy, 7 ft S groundswell, very clean. Tuesday afternoon, 11 August, is the biggest and most powerful, but only for the brave. After that, it’s a story of fading swell and dodgy wind. Get out there early in the window.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Jacone is 14 km (9 miles) from the city of Saquarema. If you plan a holiday in Rio de Janeiro, look for hotels and other accommodation in Saquarema. Saquarema has rooms for a wide range of budgets as well as car hire and transport links.
